Phenomenal, but Room for Improvement - 4 stars - November 2, 2009
As a student in Honors Algebra II, this app is incredibly handy when I'm carrying my phone, but I don't really want to lug around a big TI-84 graphing calculator. However, there are three key features that force me to use my TI-84 instead of my phone while on the go.
1) The ability to create an equation of best fit (quadratic and linear) based on a set of points. On the TI-84, you can just edit the points under the STAT button menu option, press QuadReg, L1, L2, Y2, an you have yourself a line of best fit.
2) The ability to find the x-intercepts (zeros) of a parabola. On the TI-84, you can find the intercepts by pressing the CALC button, selecting zeros, going to the graph and trace along the line above and below the x-axis.
3) As someone has already said, the ability to find the maximum/minimum value of a parabola
With these features integrated into the app, you could sell it for $4.99 and it would still end up in the Top 25.

Excellent plotter!!! - 5 stars - November 2, 2009
Very good polished, nice. Easy to use. Please implement the x=f(y) feature to give it 5 stars. The update 1.1.5 will contain polar and parametric equations, great!!!
